This invention relates to a sprinkler particularly applicable to large'commercial, 111- stallations such as -or'chards,'vineyards, truckgardens, and the like.

An object of my invention is to provide a sprinkler which willeffectively cover a large 15 fective means of breaking up the stream ofwater passing out of one of the nozzles,so that it is distributed in auniform manner close to the sprinkler itself. i

A further object is said bearing including a novel means of pre ventingthe accumulation ofsand therein;

Other objects, advantages and featuresof invention may appear from theaccompanying drawings, the subjoineddetailed description and theappended claims. a

In the drawings Figure 1 is'a side elevation of my sprinkler.

Figure 2 1s a s1de elevation of the dispei a 30 sion element.

Figure 3 is a fragmentary, longitudinal, sectional view of one ofthe'nozzles.

Figure 4: is a sectional View taken on line 44 Figure 3. i Figure 5 "s asectional View of the sprinkler body. 1

Referring more particularly to the'drawings, the numeral 1 indicates astand-pipe upon which my sprinkler is mounted.- A coupling 2 screws onto the topof the stand pipe. A journal pipe 3 screws into the cou pling2 and extends into thesprinkler. A;

A driving vane21 is placed atright'anglesto the stream of water from the nozzle 14: when the vane 20 is justentering that stream, thus forcing-the vane through the stream toeffectively break up said stream. A rotating vane 22 extends in anopposite direction from the vane 21, and serves to. throw the plate 19around so i that the larger vane 20 is againfbroiig lit into positionas'sho'wn' in Figure 1".
